Of course it wouldn't say 4 ohm dummy... -- It say's 8 ohm. (lol, sorry couldn't resist

I could be wrong here but as I'm understanding things, (imo) 99% you're going to be fine...
Could you fry the amp or a channel?... Sure, (over time). - in 10 years?
Will the amp crack up the first time you turn it on with them?... Not likely (but see the 1%).
Will the amp have to work harder to drive them? yes.
Will you have effectively cut your 85w/ch down to 65 or 70(ish) on the top end?... I think so?
Is it recommended? no.
So I would think your chances are 50/50.

Sorry I can't give you a absolute yes or no... I'm not that smart.
Speaking for me (and me only)... If I were to hook up 4's, I would NOT mix anything else in... (i.e. some 4ohm, some 8ohm on other channels) -- Of course, I wouldn't buy a set of 4 ohm speakers if I were buying. (unless they scratch an itch somewhere, so-to-speak)
